How to choose the environmental conditions and power conditions when selecting a solenoid valve?

environmental conditions

1) The maximum and minimum temperature of the environment should be selected within the allowable range;

2) In the environment where the relative humidity is high and there are water droplets and rain, a waterproof solenoid valve should be selected;
3) Special varieties should be selected for occasions where there are often vibrations, bumps and shocks in the environment, such as marine solenoid valves;

4) For use in corrosive or explosive environments, the corrosion-resistant type should be selected according to safety requirements;

5) If the environmental space is limited, a multi-function solenoid valve should be selected, because it eliminates the bypass and three manual valves and is convenient for online maintenance.

power condition

1) According to the type of power supply, select AC and DC solenoid valves respectively. Generally speaking, the AC power supply is easy to access;

2) The voltage specification is preferably AC220V.DC24V;

3) The power supply voltage fluctuation is usually +%10%.-15% for AC, and ±%10 for DC is allowed. If it is out of tolerance, voltage stabilization measures must be taken;

4) The rated current and power consumption should be selected according to the power supply capacity. It should be noted that the VA value is relatively high during AC starting, and the indirect pilot solenoid valve should be preferred when the capacity is insufficient.
